JESSE SHILLING, OF TROY, OHIO.

'MASH-COOLING MACHINE.

Specification of Letters Patent No. 17,984., dated August 11, 1857.

T 0 all whom it may concern:

Be it known that I, Jnssn SHILLING, of Troy, in the county of Miami and State of Ohio, have invented a new and Improved Mode of Cooling Mash for Distillation; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, in which Figure 1, is a vertical and central section of my improvement; (0:), (00), Fig. 2, indicates the plane of section. Fig. 2, is a plan or top view of my improvement. Fig. 3, is a detached side view of one of the outer teeth of the rake head. Fig. 4, is a detached view of one of the innermost teeth of ditto.

Similar letters of reference indicate corresponding parts in the several figures.

My invention consists in placing within the mash tub, at its center, a vertical rotating shaft having three hollow arms attached and communicating by means of a pipe with a fan box. To the hollow arms pendent hollow teeth are attached, and the parts are so arranged that as the hollow arms and the teeth rotate, the mash within the tub will be quickly cooled by current-s of cold air injected into the mash through the hollow teeth.

To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.

A, represents a mash tub, which may be constructed in the usual manner; and B, is

a vertical shaft, which is fitted within the tub at its center. The lower end of the shaft B, has a bevel wheel C upon it, and this wheel gears into a wheel D, which is placed at the inner end of a horizontal shaft E; the shaft E, being placed underneath the mash tub and having a driving pulley F, at its outer end, (See Fig. 1).

To the upper end of the shaft B, a hollow hub (a),'is attached, and three hollow arms (5), project horizontally and radially from this hub (a). The arms (1)), are about on a level with the upper edges of the tub A.

To each arm (5), hollow pendent teeth (a), are attached; three teeth are represented as being attached to each arm, but more or less may be used as occasion requires. The innermost tooth of each arm has a portion of its back side removed, or the back of these teeth do not extend entirely down to the bottom (see Fig. 4), in which (d), represents the lower end of the back of one of said teeth. The other or outer teeth have the lower parts (a of their inner sides hinged to the front sides of the teeth as shown at (e) and shares or lateral projections (f) are attached to the lower ends of the sides (a The shares'or projections are hollow and open at their back sides; the interior of the shares communicating with the teeth (0), as shown clearly in Fig. 1.

G, represents a pipe, one end of which communicates with the hollow hub (a). The opposite end of this pipe communicates with a fan box H, which is attached to one side of the mash tub. The box H, has a fan within it; the shaft I, of which has a belt (g) passing around it; said belt also passing around the driving pulley F.

The operation is as'follows: The mash, after being scalded, is cooled down to the proper temperature by means of the blast which is generated by the fan; said blast passing through the pipe G, into the hollow arms (b), and down the hollow tube (0), into the mash. The teeth and arms (5), move in the direction indicated by the ar-- rows (see Fig. 2), and the resistance or pressure of the mash against the shares or projections (f), keep said projections against the sides of the teeth; the blast passing out of the back side of the teeth. As the innermost teeth travel slower than the other ones, in consequence of being nearer the shaft B, they are not provided with hinged projections like the others, for the resistance of the mash might not be sufficient to keep the projections closed or in proper place.

The object of having the projections (f), hinged as shown to the body of the teeth (0), is to allow them to be thoroughly cleansed. This is done by placing a requisite quantity of water within the tub and rotating the arms (6), and teeth (0), in a direction reverse to that shown.

The arms (5), and teeth (a), which are usually employed are perfectly solid and merely serve the mechanical purpose of stirring mash. The mash being cooled by a perforated blast pipe which passes over the surface of the mash. By my improvement the mash is cooled in from one and a quarter to one and a half hours less time than by the usual mode.

Having thus described my invention, what I claim as new, and desire to secure by Letfan box H, the Whole being arranged subters Patent, is: stantially as described, for the purpose set 10 The hollow arms (6), with hollow teeth forth. (0), attached; said teeth, some or all, hav- JESSE SHILLING 5 ing lateral shares or projections (f), at-

tached, the hollow arms (6), being attached 'Witnesses: to a rotating shaft B, and communicating B. F. MOLUNG, with a pipe G, which is connected With a S. K. MYERS.
